EventDisplay3DService.h

Go to the documentation of this file.

//
// - Event display service used with the EventDisplay3D module to start up the
//   TApplication and allow forward, backward, and jump-to navigation of events
//   in the root input file.  This is a very much simplified version based on
//   Nova's event visplay service by Mark Messier.
